As Americans we don’t shrink from challenges, we embrace them. In the 19th century, we united the nation’s economy with the first transcontinental railroad. In the 20th century, we powered the Southwest with the largest hydroelectric power station in the world. We recognized that these challenges were not merely about laying track or building a dam, but about securing the future of our nation.

The question of how we will create, store and use energy is the great challenge of the 21st century. It threatens our economy, our security and our planet.
